The drain pipe valve is operable to be opened to facilitate a normal operation of the drain system or closed to stop water from back flowing to a sink of the drain system during an unclogging operation. The high pressure valve is operable to be turned on for supplying water to the drain unclogging system or turned off for prevent water from entering the drain unclogging system. Optionally, a pump can be installed on the high pressure hose to provide additional pressure to the water.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the present invention generally relate to plumbing devices, and more particularly to a drain unclogging system that unclogs a drain using two cutoff valves, a high pressure hose and nozzle, and a T connector.

2. Description of the Related Art

A drain is a pipe or conduit into which liquid flows and moves away from the source. They are commonly used in plumbing applications such as sinks and toilets, and as a way to remove unwanted water from areas it may accumulate in, such as basements and decks. Drains are very much a part of everyday life that perform a valuable function that usually goes unnoticed—until they get jammed, stuck or clogged. When this occurs, problems can stack up quickly and must be addressed.

Fortunately, there are many remedies for clogged drains. They range from simply jamming a coat hanger down them, to chemical solutions, to homemade remedies, and sophisticated augers and electric drain cleaners. The method of using a simple stick-like device to unclog a drain is easy and affordable, but seldom works since it usually just pushes the clogging material further down, and is unable to move around the bend of the drain. Chemical drain cleaners, like Drano, can be effective in removal of hair and grease accumulations close to the drain openings, but may not work on deeper and tougher clogs if they are too far from the source. Other considerations need to be addressed such as the safety issues of storing and using such hazardous materials. They could cause medical reactions by accidently inhaling them, or even more serious problems if they mix with previously used other chemicals in the drain.

The hand-held drain auger, or “snake,” is commonly used to unclog drains. This is a metallic cable that winds through the pipe as the operator turns a crank. It can be effective in unclogging hard to reach obstructions, but they do have a physical limit of length, and may not be able to go around the bend in the drain. They can also be difficult to operate until sufficient practice on them has been achieved. The crude steel cable in them may also damage the pipes. There are more sophisticated augers that use electricity to power them, and have a tremendous physical range in comparison to the hand-held models. These machines are able to negotiate and unclog the bends in the drain, but are most typically used by plumbers due to their high cost and need for careful operator handling.

Home remedy drain cleaners typically involve combining hot water, baking soda, and vinegar in various combinations and methods, and waiting overnight to see the results. These have the advantage of using inexpensive, readily available, and relatively safe products to clean the drain. However, these may not be as effective as the previously mentioned methods, and may take too long to see the results.

Other methods include using a cartridge of compressed air to burst the clog immediately from the drain. However, these can be unsafe to use as they are under high pressure and must be handled very carefully.

Accordingly, there is a need for a convenient, economical, and easy-to-use drain unclogging system that can be easily installed to an existing drain system and turned on and off whenever it is needed.

SUMMARY

In accordance with one embodiment, a drain unclogging system to be installed to an existing drain system is described. The drain unclogging system can be easily turned on and off as needed and does not interfere with the normal operation of the drain system.

The drain unclogging system can include a drain pipe valve installed on the drain pipe, which can be opened to facilitate normal operation of the drain system or closed to stop water from back flowing to the sink during unclogging operation, a T connector connected to a water supply valve for splitting the water supply into two water supplies—one supplies water to the sink and the other one supplies water to the drain unclogging system, a high pressure hose, a high pressure valve for connecting the water supply to one end of the high pressure hose, and a high pressure nozzle for connecting the other end of the high pressure hose to the drain pipe at a location near the U arch section of the drain pipe. Optionally, a pump can be installed on the high pressure hose to further increase the pressure of the water.

In accordance with another embodiment, a drain unclogging method using the drain unclogging system of the present invention is described. The drain unclogging method includes the steps of turning off the drain pipe valve to close the drain pipe so as to prevent water from back flowing to the sink, turning on the high pressure valve to supply water to the high pressure hose, unclogging and cleaning out any built up in the U arch section of the drain pipe utilizing the high pressure water produced by the high pressure nozzle, upon completion of the unclogging and cleaning step, turning off the high pressure valve and turning on the drain pipe valve to resume normal operation of the drain system.

Referring initially to FIG. 1, an exemplary existing drain system 10 is illustrated. As shown, the drain system 10 includes a sink 12 to hold water 13, a drain pipe 14 connected to a bottom of the sink 12 to drain the water 13 away from the sink 12, a cold water supply pipe 17 for connecting to the cold water source through a cold water valve 16 to supply cold water to the sink 12, a hot water supply pipe 19 for connecting to the hot water source through a hot water valve 18 to supply hot water to the sink 12. The main drain pipe 14 has a U arch section 15 where clogging is most likely to occur.

Referring now to FIG. 2, a drain unclogging system 100 in accordance with an exemplary embodiment of the present invention is illustrated. As shown, the drain unclogging system 100 can include a drain pipe valve 110 installed on the drain pipe 14, which can be opened to facilitate normal operation of the drain system 10 or closed to stop water from back flowing to the sink 12 during unclogging operation, a T connector 120 connected to the cold water valve 16 for splitting the cold water supply into two water supplies—one supplies the cold water to the sink 12 through the cold water supply pipe 17 and the other one supplies the cold water to the drain unclogging system 100, a high pressure hose 130 which can be either rigid or flexible, a high pressure valve 140 for connecting the cold water supply to one end of the high pressure hose 130, and a high pressure nozzle 150 for connecting the other end of the high pressure hose 130 to the drain pipe 14 at a location near the U arch section 15 of the drain pipe 14. As shown in FIG. 2 the valve 140 at two positions when open and when closed.

The T connector 120 has one inlet 122 connected to the water supply valve 16 and two outlets 124 and 126. One outlet 124 is connected to the water supply pipe 17 for supplying water to the sink 12 and the other outlet 126 is connected to the high pressure valve 140.

In FIG. 2, the T connector 120 is shown as being installed between the cold water valve 16 and the cold water supply pipe 17. Alternatively, the T connector 120 can also be installed between the hot water valve 18 and the hot water supply pipe 19 to supply hot water to the drain unclogging system 100.

The drain pipe valve 110 can be turned off so as to close the drain pipe 14 in order to prevent water from back flowing to the sink 12 during the unclogging operation. Upon completion of the unclogging operation, the drain pipe valve 110 can be turned back on so that the drain pipe 14 is open for normal operation of the drain system 10.

The high pressure valve 140 controls the water supply to the drain unclogging system 100. By turning the high pressure valve 140 on, the water is supplied through the high pressure hose 130 and the high pressure nozzle 150 to the U arch section 15 of the drain pipe 14. Upon completion of the unclogging operation, the high pressure valve 140 can be turned off so that the drain system 10 can resume its normal operation.

The high pressure nozzle 150 can increase the pressure of the water supplied through the high pressure valve 140 and the high pressure hose 130 so that any built up formed in the U arch section 15 of the drain pipe 14 can be completely removed and cleaned out.

Referring now to FIG.3, the drain unclogging system 100 of FIG. 1 with an additional pump 135 is illustrated. As shown, the pump 135 can be installed on the high pressure hose 130 at the location between the high pressure valve 140 and the high pressure nozzle 150. The pump 135 can further increase the water pressure when the water source and the high pressure nozzle 150 do not provide sufficient pressure. The pump 135 can be turned on or off based on need. Specifically, the pump is operable to be turned on to add pressure to the water or tuned off when water pressure is sufficient.

In operation, when starting the drain unclogging operation, first the drain pipe valve 110 will be turned off so as to close the drain pipe 14 in order to prevent water from back flowing to the sink 12 during the drain unclogging operation, and then the high pressure valve 140 will be turned on to supply water to the drain unclogging system 100. The water is supplied through the high pressure valve 140 and the high pressure hose 130 to the high pressure nozzle 150 where the pressure of the water will be increased and then further supplied to the U arch section 15 of the drain pipe 14 to unclog and clean out any built up in the U arch section 15 of the drain pipe 14. Optionally, a pump installed on the high pressure hose can be turned on upon determining that the water pressure is insufficient. Upon completion of the unclogging and cleaning step, the high pressure valve 140 can be turned off to stop the water supply to the drain unclogging system 100, the pump 135 if turned on can be turned off, and the drain pipe valve 110 can be turned on to open the drain pipe 14 so as to resume normal operation of the drain system.
